I've been married 33 years and still haven't the answer to a sucessful marriage...but I believe one of the reasons which helps you, is always try to share....our worries,our hopes,our joy. I paint and draw...my wife has no interest in that,..I fish now and then...again,my wife has no interest....I have an allotment....again , no interest....I go hill walking,and used to go wild camping...no interest!! We can be so very different from each other,yet we love one another...and THAT is the very thing which keeps us together through the years. After the rows,the pain,the burdens of life...love for each other holds us together and in turn,helps us solve problems that life throws at us. So my one piece of advice...let love (if you have it for each other in the first place) be your strength.Allow each other to be as different as they wish...we all need our own space....but remember the love you first felt for the other...it doesn't go away...not if you don't want it to!!
